question on x windows

[Aaron Bliss]

Hi everyone,
I'm very close to having this working properly.  Here's what's 
installed.  GDM and kde, gnome is not installed.  Here is what I'm 
seeing.  GDM is listening and accepting connections properly.
1. After logging into a session via x windows, if a user right clicks 
the desktop and selects loggoff, kde attempts to start another re-spawn 
a new display on DISPLAY 0, which of course would only work if the user 
was actually logged in at the console.  If the user just ends the x 
session (closes the client window on their computer, everything works 
and closes fine).  Is there away to remove the loggoff option from kde?
2. When a user connects to gdm (they haven't logged in yet, they are 
sitting at the login prompt) and clicks the session button and chooses a 
session that is not their default session, the desktop and kde load 
fine.  If the user does not click the session button, then kde never 
loads and all they get is a black screen, no errors or anything. 

Please advise as to how I can work around these 2 bugs.  If there isn't 
an easy workaround, I would like to possibly try kdm.  Is there a way to 
stop gdm and start kdm without restarting the box?  Thanks.
